PTT won't activate while ingame.

[Niomo]

So I'm running into an issue where PTT will not function while I go in-game. If I minimize to desktop and maximize mumble, it works perfectly fine. Obviously though, that means I cannot play while I talk! Before you ask, yes, I am running in Admin mode, I've tried to uninstall/reinstall (twice). I'm using Mumble 1.2.10.

I've been managing with Voice Activity, but my microphone picks up a lot of traffic since it's near the kitchen, so it broadcasts conversations between my wife and I and phones ringing etc.

I've attached my dxdiag. Send help!
